Calculations use calendar dates, not time of day. For birthdays on 29 February, this tool uses 28 February in non-leap years.
How does this age calculator work?
Enter your date of birth and the date on which you want to know your age. The calculator counts complete calendar years and months, then the remaining days. Total days are calculated from the difference between the two dates.
